pic with serial communication

[xloving]

i have an inertial measurement unit from sparkfun electronics..
to get the data from the module i have to sent ^g (ctrl+g) through serial..
but i dont know how to sent it from a pic..

it is directly possible from hyper terminal..
but how to send it from a c code through pic??
i am using pic16f877a with 57600 baud and hitech c compiler cor coding..

please help

CTRL G is ASCII BEL, 0x07.

send an 0x07 out the serial port, possibly followed by a CR and/or a LF, should do the trick.

Oldvan's tablet is perfect, I would add only two things:

1.
At my opinion do not send CR and/or LF.
2.
A simple calculation:
cntrl G = "G" - "A" + 1 =  71 - 65 + 1 = 7

Similarly:
cntrl A =  "A" - "A" + 1 =  65 - 65 + 1 = 1
cntrl B =  "B" - "A" + 1 =  66 - 65 + 1 = 2
...
cntrl Z =  "Z" - "A" + 1 =  90 - 65 + 1 = 26 (dec)

Yes
As the previous post from Zuisti, just send char(7) which is equivalent to Ctrl+g

if you are using hitech c just use
printf("\x007") or putch(0x07)

A simple calculation...

No calculation required, just find the letter in the table, then look at the left column on the same row.

Don't you just love hex!

yes i do... :-) and it worked perfectly fine for me..
thank you so so much and sorry for the delay in giving thanks..

also i loved working with hterm.. it shows data in hex decimal ascii and binary..
so no confusion for the recived data..
it also has a time stamp..
so its helpfull in real time coding ..
thanks a lot..
